Applications of the turbulent entrainment assumption to immiscible gas-liquid and liquid-liquid systems

摘要

The entrainment assumption,originally developed to describe mising of miscible fluid pairs,has been used successfully inprevious investigations to predict the liquid inflow velocity at the boundary of gas or vapour jets submeerged inliquids.In this paper,the power of the entrainment assumption is further revealed by the application of the Ricou-Spalding formof the assumption to the breakup of drops and jests in liquid and gas surroundings,and to liquid entrainment from initially stratified two-phase regions.
